In this paper,the topological structure of the yacht's hybrid power system is determined as the structure of the fuel cell and the battery in parallel.This paper designs a data communication scheme for energy management system based on CAN bus,and the energy management system control strategy of energy-saving switch.The above design is then integrated into the overall energy management system.Through demonstration analysis,the yacht hybrid power source shape to give priority to with PEMFC,lithium iron phosphate battery is complementary energy configuration scheme.Then this paper determine the non isolated DC/DC converter for the power conversion device.At the same time,the above are modeling in Simulink environment,and then the energy management system under the control of energy-saving switch control strategy establish the mathematical model of yacht with a complete cycle as a condition for simulation,according to the results of simulation analysis,the hybrid system structure design and control strategy design are reasonable and effective.This paper demonstrates the importance of designing a new high performance Boost converter to improve the stability and efficient operation of the yacht energy management system.This paper designs a new sliding mode algorithm to control Boost converter,and introduces the exponential approach,and replaces the symbolic function with the saturation function,which makes up the global quasi-sliding mode current loop control algorithm.The sliding mode algorithm itself shortens the approach time and weakens the chattering.The control algorithm of global quasi sliding mode current type is designed in this paper,the Boost converter to enhance robustness,and improve fast and accurate tracking performance,timely respond to the input port and steady-state output small error.It improve the quality of the bus power and demand for yachts dynamic performance and stable operation.Subsequently,the Boost converter carries out modeling and simulation experiments.to verify the effectiveness of the algorithm,and the advantages compared with the traditional algorithm.Finally,design the Boost converter prototype,and then put it in simulated small power energy management system of the cruise yacht.Under different experimental conditions,testing Boost converter performance and energy management system parameters to verify the advantage of the designed algorithm,and the effectiveness of the prototype's work,it also improve the performance of the energy management system of cruise yacht.
